Add make check target and CI workflow (#42)

Adds a `make check` target that verifies formatting (gofmt), linting (golangci-lint), and tests (go test -race) without modifying files.

Also adds `.gitea/workflows/check.yml` CI workflow that runs on pushes and PRs to main.

`make check` passes cleanly on current main.
